Drug-induced liver injury (DILI) is an important clinical problem, which has received more attention in recent decades. It can be induced by small chemical molecules, biological agents, traditional Chinese medicines (TCM), natural medicines (NM), health products (HP), and dietary supplements (DS). Idiosyncratic DILI is far more common than intrinsic DILI clinically and can be classified into hepatocellular injury, cholestatic injury, hepatocellular-cholestatic mixed injury, and vascular injury based on the types of injured target cells. The CSH guidelines summarized the epidemiology, pathogenesis, pathology, and clinical manifestation and gives 16 evidence-based recommendations on diagnosis, differential diagnosis, treatment, and prevention of DILI.

Collectively, our results support an important role for l-glutamine in regulating expression of TJPs and CRF in the jejunum of weanling piglets.

Cerebral infarction (CI), cardiovascular disease (CVD), diabetes mellitus (DM) and chronic kidney disease (CKD) are atherosclerosis-related diseases, which are major causes of health damage. For early and sensitive diagnosis, development of novel biomarkers is expected and of significant practical importance. First screening was carried out by phage expression cloning to identify antigen proteins recognized by serum IgG antibodies in patients with atherosclerosis. RPA2, LRPAP1, EEF1A1, SPOCK1, LOC729260, tubulin beta 2C (TUBB2C) and KIAA0020 markers were identified. We then compared the serum antibody levels against the candidate proteins between healthy donors (HD) and patients with CI, CVD, DM, or CKD by Alpha (amplified luminescent proximity homogeneous assay)-LISA method. The results showed that the serum TUBB2C antibody levels were significantly higher in patients with CI, DM, or CKD than those in HD. Using the average + 2SD of HD as the cut-off value, the positive thresholds of TUBB2C antibody markers were 14.8% in CI, 25.8% in DM, and 18.3% in CKD. TUBB2C antibody levels were well correlated with artery stenosis degrees such as plaque score, maximum intima-media thickness and cardio ankle vascular index. Consequently, TUBB2C antibody markers are useful to diagnose atherosclerosis, DM, and CKD, and can be applied to the prediction of the onset of CI. The serum anti-TUBB2C antibody markers are useful for the diagnosis of DM and CKD.

A B S T R A C TObjectives: Identification of the underlying pathogens of infective endocarditis (IE) is critical for precision therapy. Methods: We evaluated a metagenomic method with next-generation sequencing (NGS) for the direct detection of pathogens from the resected valves of 44 IE patients and seven rejected IE patients according to the modified Duke criteria. Results: NGS displayed sensitivity, specificity, positive predictive values and negative predictive values of 97.6%, 85.7%, 97.6%, and 85.7% compared with 46.2%, 100%, 100%, and 12.5% for blood culture and 17.1%, 100%, 100%, and 17.1% for valve culture and 51.4%, 100%, 100%, and 26.1% for valve Gram staining, respectively. Conclusions: NGS technique had superior sensitivity and shorter turnaround time compared with culturebased methods for identifying causative pathogens of IE. The NGS technology should be considered an essential supplement to culture-based methods, particularly for unculturable or difficult-to-culture microorganisms.

Background: Atherosclerosis-related life-style diseases such as cerebral infarction (CI), cardiovascular disease (CVD), diabetes mellitus (DM), and chronic kidney disease (CKD) are a serious problem in the recently aging society. The development of novel and sensitive diagnostic markers is necessary and expected for the early treatment. Methods and Results: Through the first screening by phage expression cloning, we identified ATPase, Ca ++ transporting, plasma membrane 4 (ATP2B4) and bone morphogenetic protein 1 (BMP-1) as antigens recognized by IgG antibodies in the sera of patients with atherosclerosis. The presence of autoantibodies against these antigens in serum specimens was confirmed by Western blotting. We then compared serum antibody levels against recombinant ATP2B4 and BMP-1 proteins between healthy donors (HD) and patients with atherosclerotic diseases, such as CI, transient ischemic attack (TIA), CVD, DM, or CKD, by the Alpha (amplified luminescent proximity homogeneous assay)-LISA method. The results revealed that both antibody levels were significantly higher in patients with these diseases than in HD and exhibited most prominent differences in CKD vs. HD. Correlation analysis showed that both antibody levels were well correlated with the degree of artery stenosis, such as maximum intima-media thickness with some different patterns, i.e., anti-ATP2B4 antibody levels were related to hypertension, whereas anti-BMP-1 antibodies were related to smoking habits. Conclusions:The serum antibody levels against ATP2B4 and BMP-1 can be useful diagnostic markers for atherosclerosis and its related diseases caused by hypertension and smoking habits, respectively.
